Hi guys. I bought a new tank for Flanery, a 5 gallon critter keeper. I have a filter but no heater yet. I do have a thermometer. Do you think if I put him temporarily beside one of my reptile heating lamps it will keep the water warm until I can get a heater?

He should be fine if you keep him in the warmest area of your home. At night wrap a towel around his tank to keep the warmth in. He won't become ill or die from temps in the low 70s, usually takes a while before any ill effects take place from cooler water.
